SCRAPER ATTACHMENT FOR PAIN TBRUSHES.

Application fi1ed October 27, 1920.

T 0 all whom it may concern Be it known that I, OLE J. Horn, a citizen of the United States, having residence at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Scraper Attaclr ments for Paintbrushes, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.

The purpose of this invention is to provide a painters tool of improved construction consisting of a paint brush and a scraper attached thereto, so constructed and assembled that one will not interfere with the usefulness of the other but each will contribute to the convenience of each other. The invention consists in the combination of elements and features of construction hereinafter described and shown in the drawings as inclicated by the claims.

In the drawings:

Figure 1 is a side view of a brush made according to my invention.

Figure 2 is an edge view of the same with a portion in section to disclose certain details of construction.

Figure 3 is a detail View of the scraper detached from the remainder of the tool.

The drawing shows a paint brush of usual form having the bristles, 1, attached in any convenient or desirable manner to the handle, 2.

The handle, 2, is bored at 3 at the extreme end thereof and axially with respect thereto for the reception of a wedge-shaped tang or shank, 4, projecting from the scraper blade, 5. This tang is somewhat wider at its base than the bore, 3, so that when driven into the bore in the end of the handle, it will be in ameasure selfholding.

To further insure against its accidental displacement and add to the rigidity of the device as a whole, there is provided a clamp comprising two strap members, 66, which are secured to the handle, 1, by the screws, 77, some distance from the end thereof. These clamp members are bent at 8 toward each other for a short distance and reversely bent at 9 thereafter continuing in a direction substantially parallel to each other and to the surface of the scraper, 5, and terminating in the ends, 10-10.

These bends just referred to are so formed that the ends, 1010, do not quite reach the surface of the scraper, 5, resulting in a Specification of Letters Patent.

space between them somewhat greater than the thickness of the said scraper, so that when brought together by the clamping bolt, 11 and nut, 12, the end of the handle, 2, will be tightly gripped at 13 thus providing a two-point bearing for each of the straps. 6, one at 7 and the other at 13. I

To insure that the members, 6, will not respond to a possible tendency to swing about the screws, 7, notwithstanding the frictional resistance at 13, there is provided additional means comprising a tooth, 14:, which is struck out of the body of the strap and driven into the handle at a point intermediate the screw, 7, and the end of the handle.

It willbe seen that the straps, thus them selves being securely held, provide a rigid ]o1nt at 11 for the scraper, 5; and the tang, 4, thereof which is driven into the handle provides a second point of support for the scraper blade resulting in a rigid, reliable means of connecting the two elements of the device.

The manner of using a brush or scraper is so well known that it need not be described, beyond pointing out that it is not the usual practice to scrape the entire surface to be painted but that in painting, blisters or bad spots of loosened paint are occasionally encountered and to remove or cure these defects in the surface it becomes necessary to lay aside the brush if the operator is only provided with a scraper of ordinary design and then after operating the scraper, it is pocketed or otheri'vise gotten out of hand and the painting resumed. This is especially inconvenient when the operator is so situated that he is compelled to balance himself by holding on with one hand as on a ladder or scaffold.

The convenience of the present invention will at once become apparent upon it being pointed out that this scraper is so located that the brush handle also serves as a means of holding and using it; that it is always in readiness for use; and that in most instances the workman need not even change his hold upon the brush handle in order to operate the scraper.

I claim:

1. The combination of a handle; a pair of clamping arms secured to opposite sides of the handle at one end thereof and projecting beyond the same, and a scraper blade engaged between the extendin portions of clamping arms secured to opposite sides of the handle at one end thereof and projecting beyond the same; a scraper blade between said extending arms with its working edge beyond them, and means by which said scraper blade and said arms are secured together; the scraper having a wedge-shaped tang at the side opposite its working edge and the end of the-handle being bored to engage said tang.

3. The combination of a handle; a pair of arms lapped thereon at opposite sides and projecting beyond the end of the handle; a single screw securingeach. of said arms to the handle, the extending ends of the arms being formed with registering openings; a scraper blade disposed between the extend ing ends of said arms and a fastening memher which passes through the registered openings and the blade, said arms each having a tooth formed at a distance from the securing screw and projecting inwardly to engage the handle to prevent pivotal movement of the arm about the screw.

4. The combination of a handle; a pair of arms lapped thereon at opposite sides with their endsprojecting beyond the end of the handle, each arm being formed with a hole near each end and with a tooth projecting inwardly into the handle intermediate said holes; fastening means in the holes adjacent the handle securing the MI'IJS thereto; an apertured scraper blade and a clamping bolt engaging its aperture and the holes in the extending portions of the arms for securing the blade between the latter, said blade having a tang and the end of the handle beingbored to receive said tang to prevent pivotal movement of the blade on the bolt.

In testimony whereof, I have hereuntoset my hand this23rd day of October, 1920.

OLE J. HOPE.
